Budget gaming build that can handle most
newer games. Offers great value for money.

High/ultra in solo content. High/medium in a 10-man raid setting. Medium in a 25-man raid setting. Money can be saved by:
- Getting a cheaper CPU, e.g. an Intel Celeron G530. Mind though that WoW tends to favor a powerful CPU.
- Going for a cheaper H61 motherboard, but I doubt you will find anything that is much cheaper. Maybe $10 saved.
- A cheaper GPU. A Radeon 6670 or a nVidia GT 440 would still yield playable framerates on high/ultra in solo content (shadows/sunshafts off), even at a 1080p resolution.
- Changing the GPU also means you can get a cheaper PSU. The NAXN 350W will be enough for a G530 together with a GT 440.
- Any mid-tower case would do fine, as long as it can house all the components. A really cheap case can be had for $20.
- You can always drop down the HDD to a lower capacity and/or slower drive.

I currently play WoW with an i3 2100 and a gts 250 @ 1080p with everything ultra except for shadows on low, water on low, sunshaft off and particle density low. In a raid you're not likely to notice shadows or water quality and particle density is just eye candy, but you can't afford it! In 25mans I don't dip below 25 fps and stay at an average of 50fps, which is still very playable. So spend a little less on that gpu and get an i3 21** series cpu and a slightly less powerful gpu and you'll be perfectly fine. I got lucky and bought my gts 250 for about 50$ so I'm sure you could find it at a decent price as well, though the people on this forum won't be too on board with the suggestion of buying a dx10 gpu....

From the looks of it, my last computer was running just below that and I could run everything at low-mid setting at around 20 FPS. Although not ideal, it didn't really affect my performance. I don't think it would really be possible to build that setup nowadays (it would have to be used), but the low-end builds from Marest and Chaud will kill WoW for less than 600$ easily.
